Do its wrong parts get eaten? (5)

Ross

I believe the answer is:

sprat

I'm a little stuck... Click here to teach me more about this clue!

'do' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'its wrong parts get eaten?' is the wordplay.
'parts' anagrams to 'SPRAT'.
Though, I'm not clear how this is indicated.

Can you help me to learn more?

(Other definitions for sprat that I've seen before include "'Set a . . . . . to catch a herring'" , "Traps for small fish" , "Tiny fish" , "Couple sharing meat" , "Small food fish" .)

I've seen this clue in the Evening Standard.
